sound issue

when ever there is no player open or any app that is made to produce sound, other then windows, a faint static can be heard at all times. when the mouse is moved another sound is mixed in with the first, again its very faint. when a keystroke is made a thrid differant sound is made and yes again its faint. all three of these sound can be done at once if i'm typing and moving the mouse around at the same time. i have tried two sound card types, the On board sound and a pci sound card both produce the same sounds. and another thing if i'm am opening an app lets say adobe photo shop, my player skips. mp3s dont skip.. theres some thing startge going on here, heres some system specs.

Chipless on-board sound, also known as AC '97 (audio codec 1997) will cause this problem for two reasons:

1. Being on the motherboard, it's more subject to digital noise due to its proximity to digital circuitry (and the fact that part of the audio circuitry is on the same chipset that's doing the digital work); and

2. Since the CPU is doing the actual work of the digital-to-analog conversion, the sucked-up cycles cause little "hiccups" that are audible.

A PCI sound card will both sound better and improve performance. A SoundBlaster Live! (the minimum that I recommend) will cost as little as $30 in the OEM version.
